I finally got my boat registered in NJ. I had to return the boat to USCG documentation in order to do this. At DMV they gave me a new title and registration with numbers. Letter from USCG clearly states that "A documented vessel may not be titled by a State...46 USC 12106(a)" Also, should I display NJ registration numbers on the boat? At DMV they told me to display NJ registration numbers, but NY broker tells me that I can't display NJ numbers if the boat is documented. Can anybody help? This is way too confusing.
